Top 10 went from 31% to 28% in the last 3 days.
The last 5 days BTC price rentered 3XX price, so people might be buying btc and w8 for pump.
In addition, good stable coins with clear roadmaps, like XC, are prone to manipulation, in essence, people use the roadmap to arrange their short term investments: in this case, we know that more blocknet ITO information will be available due Monday.
Those factors combined, along with others probably as well, resulted in fixing the lower max holders %. Maybe it has also to do with the complete pre-weekend mintpal breakdown. I am actually so certain of the next price movements and general trend that I put in some fiat and bought more XC at 105k, fun fact is I knew price would dump to sub 100k again but when it comes to XC im just way too greedy I want every coin I can get in my hands asap.
BTW, everytime you feel uncertain about XC and its course, I urge you to check at some of XC's past competitors(at least anon related), most of which held bigger prices than XC for at least a couple of months each: DKR/RZR/CLOAK/MNRO etc, XC is a safe haven compared to most.
